Brakes
The brake pedal is used to apply the vehicle'sregular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. Ifone brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect.
WARNING
The power brakes only work when the electricmotor or combustion engine is running.
If the brake pedal is used when the engine isswitched off, greater pressure must be applied tobrake the vehicle.
In very hilly areas or when driving with a heavyload, gear position B can be used to augment thebrakes with engine braking.
Use the Off Road drive mode to increase theengine braking effect when driving on steepdowngrades at low speeds.
Anti-lock brakes
The vehicle is equipped with an Anti-lock BrakingSystem (ABS), which helps prevent the wheelsfrom locking and helps maintain steering controlwhen braking. Vibrations may be felt from the
brake pedal when ABS is operating, which is nor-mal.
After the vehicle is started, a brief test of theABS system is automatically performed when thedriver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.
Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor braking function is used. This converts thevehicle's kinetic energy into electrical energy,which is used to charge the hybrid battery. Whenthe battery is being charged with the electricmotor braking function, this will be indicated inthe instrument panel.
When the battery is being charged with the electricmotor braking function, this will be indicated in theinstrument panel.
This function is active at speeds in the range of150-5 km/h (93-3 mph). When braking atspeeds outside of this range, or during harderbraking, the hydraulic braking system is used toaugment braking. This is indicated in the instru-ment panel with the pointer down in the red area.

WARNING
If the warning symbols for both brake faultand ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is normalwhen this occurs, drive carefully to thenearest workshop to have the brake sys-tem checked - an authorized Volvo work-shop is recommended.
If the brake fluid has fallen below the MINlevel in the brake fluid reservoir, the vehi-cle should not be driven until the brakefluid has been filled. The reason for thebrake fluid loss must be checked.

Brake Assist System
The brake enhancing system, Brake AssistSystem (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habitsand increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.

Brakes (p. 435)
Braking on wet roads
Prolonged driving in heavy rain without brakingmay cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. Itwill then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead.
Firmly apply the brakes after washing the vehicleor driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.

Braking on salted roads
When driving on salted roads, a layer of salt mayform on the brake discs and brake pads.
This could increase stopping distance. Maintainan extra large safety distance to the vehicleahead. Make sure to also:
Apply the brakes from time to time to helpremove salt. Make sure braking does notpose a risk to any other road users.
Gently apply the brakes when you have fin-ished driving and before driving again.

Starting and stopping thecombustion engine in Twin Enginevehicles
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time. When driving on only the electricmotor, the vehicle may automatically start thecombustion engine due to outside circumstan-ces, e.g. low ambient temperatures. This is com-pletely normal. The combustion engine will alsoalways start when the hybrid battery is nearlyfully discharged.
Climate settings at low temperatures
At low ambient temperatures, the combustionengine will sometimes start automatically to helpachieve the desired passenger compartmenttemperature and air quality. The amount of timethe combustion engine is running can be affec-ted by:
lowering the temperature
reducing blower speed
activating Pure drive mode.
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, theelectric motor's driving range and power may bereduced and affect how often the combustionengine automatically starts.
Emission control system
To help ensure that the emission control systemfunctions optimally, the combustion engine willrun for several minutes after it is started. Theamount of time the combustion engine needs tobe used varies depending on the temperature ofthe three-way catalytic converter.
WARNING

Leveling control* and suspension
The vehicle's leveling control system adjusts thesuspension and shock absorbers automaticallyto help provide good comfort and control whiledriving. Leveling can also be controlled manuallyto facilitate loading or getting in and out of thevehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drivemode and vehicle speed. The pneumatic suspen-sion reduces the vehicle's ground clearance athigher speeds to reduce air resistance andincrease stability. The shock absorbers are nor-mally set to provide the best possible comfortand are adjusted continuously according to theroad surface and the vehicle's acceleration, brak-ing and cornering.
The instrument panel indicateswhen the suspension level isbeing adjusted.
The following apply if a door or the tailgate isopened:
If a door is opened, the level can only beadjusted upwards.
If the tailgate is open, the level can only beadjusted downwards.
Parking
When parking, make sure that there is adequatespace above and below the vehicle since groundclearance may vary depending on e.g. ambient
temperature, how the vehicle is loaded, if loadingmode is used, which drive mode is selected afterthe engine is started, etc.
The level may also be adjusted a period after thevehicle is parked. This is to compensate for anyheight changes that may occur due to tempera-ture changes in the air springs when the vehiclecools.
Transporting
When transporting the vehicle on a ferry, train ortruck, only secure (lash) the vehicle around thetires, not using any other parts of the chassis.Changes in the pneumatic suspension may occurduring transport, which could adversely affect thelashing and result in damage.

Recommended tire pressure
The tire pressure placard on the driver's side Bpillar (between the front and the rear door) indi-cates tire pressure for different loads and speedconditions.
The decal specifies the designation for the fac-tory-mounted tires on the vehicle, as well as loadlimits and inflation pressures.

Approved tire pressure (p. 673)
Tire pressure monitoring system*
The tire pressure monitoring system6 provides awarning symbol in the instrument panel if pres-sure is too low in one or more tires.
SymbolExplanation
This symbol illuminates to indicatelow inflation pressure.
If there is a system malfunction, theinflation pressure warning symbolwill flash for approximately oneminute and then glow steadily.
System description
The tire pressure monitoring system measuresdifferences in rotational speed between thewheels through the ABS system to determine ifthe tires are properly inflated. If inflation pressurein a tire is too low, its diameter (and consequentlyits rotational speed) changes. By comparing thetires with each other, the system can determine ifthe pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoringsystem is generally referred to as TPMS.
Each tire, including the spare (if provided)7
should be checked monthly when cold and infla-
ted to the inflation pressure recommended by thevehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.)
As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure.
Driving on a significantly under-inflated tire cau-ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tire
